Underwater hull inspection and technical attendance

SVC undertook an underwater hull inspection at anchorage on 15 October 2026. The work-done report records the inspection, attendance transport and permission arrangements as completed. A separate line records technicians surveying the vessel’s cranes and auxiliary engine.

The underwater inspection and machinery survey were distinct tasks within the attendance. The inspection record establishes the work undertaken; it does not establish a particular defect, a class acceptance or a subsequent repair outcome.

Keep the underwater scope and machinery questions distinct

A hull inspection answers a different question from a crane or auxiliary-engine survey. For an underwater attendance, the superintendent should identify the areas to inspect and the reason for requesting the dive. A suspected impact, fouling concern or vibration complaint calls for different views and follow-up information.

For a new combined attendance, send the machinery worklist separately: the crane or engine identification, reported symptoms and available maintenance records help SVC prepare the appropriate technicians. The completion of an inspection alone should not be treated as evidence that an unreported fault has been repaired.

Photographs should identify the area being inspected

Underwater photographs are useful when the vessel can relate each view to the inspected surface. For a new dive, agree the areas requiring coverage and the reporting required before attendance. Hull plating, propeller, rudder and intakes should be identified separately where they form part of the requested scope.

Visibility, access and the vessel’s operating condition affect what can be observed. If an area cannot be inspected, record that limitation rather than treating a missing view as a satisfactory finding. Any recommendation for cleaning, further inspection or repair needs the corresponding observed evidence.

Arrange an underwater inspection during the port call

Send SVC the port or anchorage, ETA and working window, vessel dimensions, reason for inspection and the nominated underwater areas. Include any required owner or survey attendance and the expected photographs, video or written report. SVC can then define the dive and related onboard technical work in the quotation.

For port-specific planning, see underwater inspection in Vung Tau, underwater inspection in Nha Trang and ship repair services in Vietnam. These service pages describe the next attendance; they do not extend the recorded location or findings of this case.
